Door fastener



Nov. 22, 3.932. E. J. DQWLMG DOOR FASTENER Filed April 15, 1951 Patented Nov. 22, 1932 UNITED STATES EDWARD JOHN BOWLING, OF PAWHUSKA, OKLAHOMA DOOR FASTENER Application filed April 15,

This invention relates to door latches or door fasteners and more particularly to those of the portable type designed to be used in addition to the usual lock found on doors.

A primary object of the invention is to provide a door fastener which may be applied or removed as a unit without disassembling and without the use of tools and which when applied will securely hold the door against opening from the outside.

Another object of the invention is to so construct a fastener that it will have a maximum bracing effect and which may be used on all doors regardless of whether the surface of the door and frame be on the same level or not.

Still another object is to so construct such a fastener that the braces will slide around on the blade out of the way to permit opening or closing of the door, the fastener being permitted to remain on the frame.

In carrying out these objects, the invention is susceptible of a wide range of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention; there being shown in the drawing for illustrative purposes a preferred and practical form, in which:

Figure 1 represents a perspective view of a portion of a door and frame with this improved fastener shown in operative position thereon;

Fig. 2 is a horizontal section through the fastener taken on the line 2-2 of Fig. 1; and

Fig. 3 is a perspective view of the members constituting the fastener shown in juxtaposition ready for assembly, the bolt and thumb screws being omitted.

In the embodiment illustrated the fastener 10 constituting this invention is shown in connection with a door D, a frame or casing F and a stop S, a portion only of each being illustrated in section merely to illustrate the method of using the fastener.

The fastener consists essentially of a frame engaging plate or blade 11 having one end bent inwardly at a right angle to form a door 1' am engaging toe 12 which is designed when the device is applied to enter a recess R such as usually found in the door am for 931. Serial No. 530,342.

the reception of the latch or bolt and which s notherein shown. The blade or plate 11 is designed to be located between two brace me1nbers13 and 14 here shown L-shaped in form and constructed of heavy strain resisting material, the outer ends of the long arms of which are apertured as shown at 15 to register when assembled with a similar aperture 15a carried by the outer end of the plate 11 and through which is designed to pass a bolt 16 for securely clamping these plates together and which holds them in assembled relation and yet provides sufficient play to permit the plates 13 and 14 to swing on the i W bolt relatively to the plate 11. One of the L-shaped brace members is shown longer than the other, 14 being the one here shown to adapt the fastener for use in connection with doors which are not on the same level with the casing or frame as shown clearly in Fig. 2. Carried by the short arms 17 and 18 of the brace plates are two thumb screws 19 and 20 which have threaded engagement with apertures 21 and 22.. These thumb screws are provided at their inner or clamping ends with heads 23 and 24: designed for clamping engagement with the door frame and the door when the device is applied.

" These clamping heads or caps 23 and 24 are free to turn on the thumb screws 19 and 20 so that they may be tightly engaged with the face of the door or frame by turning of the bolts or screws 19 and 20 without marring the surfaces of these parts such as would occur if these caps were made fixed to the screws.

The fastener is applied to the door j am or frame when the'door is open by inserting the toe 12 through an aperture R in the keeper plate K. The brace member 13 is then at way of the door D which is shown in dotted lines in'Fig. 2 and when so positioned the door may be closed from such dotted line position. After the door has been closed the brace 14.- is swung back into position shown in Fig. 2 and the clamping bolt or screw 20 is screwed home to cause the head 24 thereof to securely engage the door D.

With the fastener applied as shown in Fig. 2 the braces 13 and 14 are arranged on each side of the blade 11 the toe 12 of which has hooked engagement with the frame. It will thus be seen that one of these brace members fits tightly against the door and the other against the door frame with the blade 11 between them. These braces or shoes 13 and 14 are independently adjustable to fit doors and frames of different characters or rather those located in diflerent planes. To open the door all that is necessary is to loosen the screw and swing the member 14 into the dotted line sition shown in Fig. 2 and the door may readily opened and closed.

The gist of applicants invention resides in the arrangement of the two slidable or swingable braces mounted on the blade 11 and adapted to be swung out of the way for closing or opening the door and which provide a unitary structure which does not have to be taken apart to put it on or to take it off.

This fastener 10 may be carried around by a person who travels and in the use thereof the room door is opened and the toe 12 engaged with the opening in the keeper plate which is found in all standard door and lock installations. "he device when the door is closed is firmly held anchored with its main body portion projecting outwardly from the face of the door. The member or brace rod 13 is then fastened to the door frame, as shown in Fig. 2, and the brace 14 is swung into position and engaged by means of the screw member 20 with the door D and thus the blade which is engaged with the frame is braced on both sides and the door firmly held against opening from the outside, thus insuring privacy and protection to the occupant of the room.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.

I claim:

A portable door fastener comprising a blade having a laterally disposed lug at one end for entry into the keeper recess in the jamb of a door, the opposite end of the blade projecting outwardly from the door face, L- shaped braces arranged upon opposite sides of the blade, each brace including a straight side in flat contact with the blade and a laterally projecting foot, a pivot for swingably connecting the outer ends of the braces with the outer end of the blade so that the braces will have swinging contact with the blade when the braces are swung outwardly from EDWARD JOHN DOWLING.
